Actually, an invasion is more dangerous to them, because it would open the floodgates on population transfer, which is something that the neighbouring couintrjes are not too keen on happening. China doesn't want millions of refugees flowing into their country, so that's one main reason they don't invade. North Korea knows that. And you just said that threatening is more profiting than actually doing something, which is my whole point: they're not going to nuke them because they risk too much doing so.

Here the trumpians were saying it would be hillary that would start world war 3.

Do they really care though? All they've done is basically begging the rest of the world to invade them like a spoiled child trying to test his limits. If anything they believe no one would dare. I don't really see fear in any of their actions.

I wouldn't be so sure about that. Being pampered your whole life only being fed propaganda warps your mind. Look at any dictator in history. You do a lot of stupid things without thinking of consequences when all you get to hear everyday is how great you are and that you cannot possibly fail.

Look at Trump.

Why should they believe that anyone would dare? It hasn't happened since 1953, despite them committing terrorist attacks, assassinations, developing nuclear weapons and threatening other countries.

Which is my point. They don't fear anything, not even possible repercussions after a deliberate attack.

For a nuclear attack they would. They've shelled South Korea since they've gotten nuclear weapons, sinking a shit and killing the people onboard. However, they have not used any nukes yet, because they know that they wouldn't be able to get away with it.

I doubt this alliance would last for long if North Korea goes to war with China's more economically valuable trading partners.

Yeah sure, that's where they draw the line. Because moderation, levelheadedness and fear is all that North Korea is about. I don't think so. If they had nuclear weapons and if the provocation against them is big enough they will gladly push the button.

Please try to think like a dictator and not a rational person. Those things are mutually exclusive.

The North Korean leadership are not stupid. There's a reason they've been able to last this long, despite the collapse of the Soviet Union, extreme famines and immense poverty: they know when to get entangled and how to not cross the line.

Two horrible leaderships continuing their stupid fight. One makes hell for its citizens the other makes hell for citizens of other nations particularly in the middle eastern region
